Groundworks in Great Amwell, Hertfordshire
In Great Amwell and across Hertfordshire, well-delivered groundworks ensure buildings, extensions and external structures remain strong and stable for years to come. Caltom Construction provide groundworks that are tailored to the property, soil conditions and design requirements of each project. We take time to understand what the structure will be supporting and how the space will be used, then plan the excavation, foundations and drainage accordingly.
Our goal is to create a solid, well-drained and compliant base that reduces future issues and supports a high-quality finish above ground.
Reliable groundworks for projects in Great Amwell, Hertfordshire
Every successful build in Great Amwell, Hertfordshire starts below the surface. If the groundworks are rushed, poorly planned or carried out without proper care, problems can appear later in the form of movement, cracking, drainage issues or water ingress. Caltom Construction provide reliable, carefully managed groundworks services throughout Great Amwell and the wider Hertfordshire area, focusing on preparation, accuracy and long-term stability.
We handle excavations, footing preparation, concrete pours, service trenches, drainage runs and external bases in a structured way, making sure levels, depths and falls are correct before any concrete or finishes are installed.
Our core groundworks services
In Great Amwell we support domestic, commercial and development projects with a full range of groundworks, including site strip, reduced level digs, foundations, trench fill, drainage, soakaways, concrete bases, retaining structures and external slab preparation. Our focus is on doing the fundamentals properly so that every subsequent stage of the project benefits.
We carry out excavation for foundations, drainage, trenches, utility installations and full-site preparation. Our team remove soil, debris and unsuitable ground, shaping and levelling the site exactly as required. With proper machinery, controlled digging and safe working practices, we leave every site ready for accurate construction and prevent issues such as uneven settling or poor compaction.
A stable sub-base is essential for slabs, driveways, footpaths and hardstanding. We supply and install high-quality MOT Type 1 and other engineered aggregates, compacted in layers to ensure maximum stability and load-bearing performance. Whether it’s for a domestic driveway or a commercial yard, we create strong and durable sub-bases that prevent sinking, cracking and water retention.
Proper drainage protects your property and prevents long-term structural damage. We install surface water systems, soakaways, pipe runs, manholes, gullies and service trenches for utilities. Our team ensure all drainage gradients are correct, flows are unobstructed and the system integrates seamlessly with your property or development. Effective underground preparation reduces the risk of flooding, blockages and future remedial work.
